1ST STiH407 USB PHY controller 2 3This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3 4host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics. 5 6Required properties: 7- compatible : should be "st,stih407-usb2-phy" 8- st,syscfg : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets 9- resets : list of phandle and reset specifier pairs. There should be two entries, one 10 for the whole phy and one for the port 11- reset-names : list of reset signal names. Should be "global" and "port" 12See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml 13See: Documentation/devicetree/bindings/reset/reset.txt 14 15Example: 16 17usb2_picophy0: usbpicophy@f8 { 18 compatible = "st,stih407-usb2-phy"; 19 #phy-cells = <0>; 20 st,syscfg = <&syscfg_core 0x100 0xf4>; 21 resets = <&softreset STIH407_PICOPHY_SOFTRESET>, 22 <&picophyreset STIH407_PICOPHY0_RESET>; 23 reset-names = "global", "port"; 24};
